HydroxyPropyl methylcellose (HPMC) uye iyo methylcellose (mc) mumatare akasiyana, kubva pamishonga yemishonga uye chikafu chekuvaka uye kutarisira kwemunhu.
Cellulose Denivatives inokatyamadzwa mune dzakawanda maindasitiri nekuda kwezvivakwa zvavo zvakasiyana uye zvinoshandiswa. Pakati peaya erivatives, hydroxyprusyl methylcellose (HPMC), methylcellulose (mchylcellulose (mchylcellulose (hydroxylchyl celleryl cellever (cmc) inoshandisa kushandiswa kwavo kwakapararira uye kusiyanisa hunhu.
1.comemical Zvivakwa:
Hydroxyprusyl methylcellose (HPMC):
HPMC iri synthesized kubva ku cellulose kuburikidza nemakemikari kugadziridzwa kunosanganisira kutsiva kwemapoka ehydroxyl nemethyl uye hydroxyprupropyl mapoka. Degree rekutsiva (DS) inosanganisira zvivakwa, kusanganisira viscosity uye solubility. Hpmc's Chemcal Chimiro chinopa zvinhu zvakanaka firimu-kugadzira zvivakwa uye mvura yekuchengetwa kwemvura, ichiita kuti iite yakakodzera kune dzakasiyana siyana application.
MetHylcellose (MC):
MC inotorwa kubva ku cellulose nekutsiva hydroxyl mapoka ane methyl mapoka. Kusiyana neHPMC, mc licks hydroxyprupropyl mapoka. Zvivakwa zvayo zvinokonzerwa nezvinhu zvakadai sedanho rekutsiva uye suremu. MC inoratidza yakanakisa mvura yekuchengetwa uye inokakavara zvivakwa, ichiita kuti ive yakakosha mumaindasitiri senge mishonga yemishonga uye chikafu.
HydroxytHyl Cellulose (Hec):
Hec yakashongedzwa nekuregererwa kwemheremalose ine ethylyone oxide. Iko kusuma kweiyo hydroxytethyl mapoka anopa midziyo yakasarudzika yakadai seyakanyanya kuremerwa kugona uye pseudoplasticasity. Hec inozoshandiswa zvakanyanya mune zvigadzirwa zvega zvega, pendi, uye zvinonamatira nekuda kwekudzora kwayo kwerateological kudzora uye mafirimu ekugadzira mafirimu.
Carboxymethyl Cellulose (cmc):
CMC inogadzirwa nekuita cellulose ine chloroacetic acid kana yayo sodium munyu. Zvikwata zveCarboxyMethyl Mapoka anounzwa, anovandudza zvivakwa zvakaita seyakagadziriswa mvura, yekuvhara, uye kugadzikana. CMC inowana mafomu mune chikafu, mishonga yemishonga, uye kuyerera kwemafuta nekuda kwekuita kwayo, kusimbisa, uye kusunga zvivakwa.
2.Properties:
Viscosity:
HPMC, MC, Hec, uye CMC Exhibit Yakasiyana Miscossity mazinga anoenderana nezvinhu senge degree rekutsiva, uye kusungirirwa. Kazhinji, HPMC uye MC Govera Superior Viscosity Control Control kana kuenzaniswa neHeC uye CMC, ine HEC inopa yakanyanya kuremerwa nekubudirira kwepasi pakukora.
Kuchengeta mvura:
HPMC uye MC anayo Mvura Yakanakisa Kugona Kwekugona Kukanganisika, yakakosha pane zvekushandisa zvinoda kunyorova kuchena nekuburitswa kwenguva refu. Hec inoratidzirawo midziyo yemvura yakanaka, nepo Cmc inopa ichichengetedza mwero yekuchengetwa kwemvura nekuda kwekunetseka kwayo kwakanyanya.
Film Ford:
HPMC uye HPM inozivikanwa nekugona kwavo kuumbwa-firimu. Kugonesa kuvandudzwa kwemavara ane coherent uye anochinjika. MC, kunyangwe inokwanisa kugadzira mafirimu ekuumba, anogona kuratidza brittleness kana achienzaniswa neHPMC uye Hec. CMC, kunyanya inoshandiswa seyekuita mumiriri uye inosimbisa mumiririri, ine mashoma mafirimu-ekugadzira mafirimu.
Solubility:
Mese mana cellulose anobva kune svutugadzike mvura yemvura kusvika pamwero wakasiyana. HPMC, MC, uye CMC yakanyungudutswa nyore mumvura, nepo hec ichiratidzira yakaderera solubility, inoda kupisa kwakanyanya kwekuparadzwa. Pamusoro pezvo, iyo degree rekutsiva dzinopesvedzera iyo solubility yeaya majekiti.
3.Application:
Mishonga:
HPMC uye MC inoshandiswa zvakanyanya mukuumbwa kwemishonga sezvikwangwani, zvinoparadza, uye vanodzora-vamiriri-vanozvidzora nekuda kwezvinhu zvavo zvekubuda uye zvakasarudzika kuburitswa. Hec inowana zvikumbiro mumhinduro dzeOPHThalmic uye mafomu epamusoro ekuisa kujekesa kwayo uye viscosity control. CMC inoshandirwa mumuromo momuromo uye mahwendefa ezvipfuyo zvine simba uye kusimbisa mhedzisiro.
Indasitiri yechikafu:
CMC inotora basa rakakosha muindasitiri yechikafu seanorira, stabilizer, uye mafuta ekutsiva mune zvigadzirwa senge ice cream, sosi, uye zvinhu zvinobayiswa. HPMC uye MC inoshandiswa mune zvekudya zvekudya zvekuremerwa kwavo, gelly, uye mvura-inosunga midziyo. Hec haina kujairika asi inogona kushandiswa mukunyorwa kwakadaro seyakaderera-calorie chikafu uye zvinwiwa.
Kuvaka:
HPMC inowanzo shanda zvakanyanya mumidziyo yekuvaka senge motars MC inoshandiswawo mune zvikumbiro zvakafanana, zvinobatsira kuti zvidzivirirwe kusawirirana uye kubatana. Hec inowana mashoma kushandiswa mukuvakwa nekuda kwemutengo wayo wepamusoro uchienzaniswa neHPMC uye MC.
Zvigadzirwa zvega zvega:
HEC uye HPMC yakapararira yezvigadzirwa zvega senge shampoos, marara, uye mafiriya sekurema, stabilizders, uye mafirimu. Kuenderana kwavo nehuremu hwakawanda hwekuita cosmetic zvimisikidzwa uye kugona kwavo kusimudzira kuita kwechigadzirwa kunoita kuti vazvikuve mukuumbwa. CMC inogona kushandiswa mune niche application mukati mechiremba wekutarisira wega nekuda kwekusimbisa kwayo uye kwakakora zvinhu.
4.Inindustrial kukosha:
Iko kukosha kweHPMC uye iyo yayo inofamba ichirara mukuwanda kwavo uye kushandurwa kwekuyambuka maindasitiri akasiyana siyana. Aya maCellulose anobva anoshanda sezvinhu zvakakosha mukuumbwa, kupa kune zvigadzirwa zvechigadzirwa, kuita uye kushanda. Zvivakwa zvavo zvakasiyana siyana zvinovaita kuti vave vanokatyamadza muzvikamu zvakadai semishonga yemishonga, chikafu, kuvaka, uye kutarisirwa kwako, kutyaira nekukura kwemusika.
HydroxyPropyl methylcellose (HPMC) uye iyo methivives, inosanganisira methylcellulose (Hydroxylmel Cellen Cellulose Nepo aya mheremhondi anobva kugovana kugovana zviitiko zveMakemikari uye Solubility yemvura, ivo vanoratidza maitiro akasiyana siyana maererano neVanhu vezvevaridzi, kuchengetedza kwemvura, kuumbwa kwemvura, uye solubility. Kunzwisisa izvi kusiyana kwakakosha kuti ugadzirise kushandiswa kwavo kune maindasitiri, achikurudzira austring, uye achirovera hupfumi.
